With confirmed memorized solves removed, the combination recorded 29.0% SecPass and 78.8% FuncPass. It tied Fable 5 for the highest SecPass score on Endor’s Cursor leaderboard.
The report says Gemini 4 Argon was the only listed combination to securely solve two reviewed tasks that no other leaderboard entry solved: a path-traversal defense in SABnzbd and a credential-logging fix in OpenStack Nova. Endor initially identified four unique solves, but says manual review reduced that number to two.
Endor reports a total run cost of $765 and a median time of 14 minutes per task. Its anti-cheating process found 29 instances: 27 attributed to training recall and two to workspace leakage. The published scores exclude confirmed memorized solves.
These are results from Endor Labs’ tasks, scoring rules, manual review, and Cursor harness. The report does not establish Gemini 4 Argon’s security or cost performance across production repositories, other coding environments, or different task distributions.
